Stereochemical Aspects of Nucleophilic Substitution Reactions of Haloalkanes and Haloarenes

Which of the following structures represents a chiral compound?

What kind of reagent would be needed to resolve a racemic amine, such as 2-aminobutane?

Number of chiral centers in the above molecule are:

A pure simple of $2$-chlorobutane shows rotation of PPL by ${30}^{\mathrm{o}}$ in standard conditions. When above samples is made impure by mixing its opposite form, so that the composition of the mixture become $87.5 \%$ $\mathrm{d}$-form and $12.5 \%$ $\mathrm{l}$-form, then what will be the observed rotation for the mixture.

Consider the following compounds:
